Task Control Instructions
Section 3-34
• Extra cyclic tasks (CS1-H, CJ1-H, and CJ1M CPU Units only):
N must be a constant between 8000 and 8255 decimal. (Values 8000 to
8255 specify extra cyclic tasks 0 to 255.)
Operand Specifications
Description
TKON(820) puts the specified cyclic task or extra cyclic task in executable sta-
tus. When N is 0 to 31 (specifying a cyclic task), the corresponding Task Flag
(TK00 to TK31) will be turned ON at the same time.
This instruction can be placed in regular cyclic tasks only. It cannot be placed
in an extra cyclic task or interrupt task.
The cyclic task or extra cyclic task specified in TKON(820) will be also be exe-
cutable in later cycles as long as it isn’t put in standby status by TKOF(821).
Any task can be made executable from any cyclic task, although the specified
task won’t be executed until the next cycle if its task number is lower than the
task number of the local task. The task will be executed in the same cycle if its
task number is higher than the local task’s task number.
